Definitions

  • the present invention relates in general to a seat assembly for a motor vehicle, and more particularly to a seat assembly equipped with a seat belt.
  • FIG. 5 of the accompanying drawings which is generally designated by numeral 1.
  • the seat assembly 1 comprises a seat cushion part 2 and a seat back part 3.
  • a known reclining mechanism is arranged between the parts 2 and 3 to allow a tilting movement of the seat back part 3 relative to the seat cushion part 2.
  • Parallel upper rails 5a and 5b are secured to lower side frames 4a and 4b of the seat cushion part 2.
  • the upper rails 5a and 5b are slidably disposed on parallel lower rails 6a and 6b which, in turn, are secured to rectangular rotatable frame 7.
  • a known position lock device is arranged between the upper and lower rails to lock the upper rails at a desired position relative to the lower rails.
  • the rotatable frame 7 is rotatably disposed on a support member 8 which is stationarily mounted on a vehicle floor 9.
  • the rectangular rotatable frame 7 is formed at its depressed center portion with a circular opening 71.
  • the peripheral edge 72 of the circular opening 71 is slidably disposed in a circular groove 82 formed on an upper raised portion of the support member 8.
  • Designated by numeral 81 a circular opening formed in the raised center portion of the support member 8, about which is defined the circular groove 82.
  • the seat assembly 1 is equipped with a seat belt assembly, more particularly, a lap belt assembly which comprises a buckle member 10a fixed to a first belt portion 10c and a tongue member 10b fixed to a second belt portion 10d.
  • the first and second belt portions 10c and 10d are connected to the lower side frames 4a and 4b of the seat cushion part 2 through respective retainers 11a and 11b.
  • connection of the seat belt assembly to the seat assembly has been given little thought.
  • such connection has been made by using only the retainers 11a and 11b fixed to the lower side frames 4a and 4b of the seat cushion part 2.
  • a big load is entirely applied on the retainers 11a and 11b. This induces sometimes deformation and/or breakage of the frames 4a and 4b of the seat cushion part 2 because the durability of these frames to such shock is usually poor.
  • a seat belt-equipped seat assembly mounted on a vehicle floor
  • the seat assembly comprising a seat proper including a seat cushion part and a seat back part, a structure mounted on the vehicle floor, a seat sliding mechanism including a pair of upper rails secured to the seat cushion and a pair of lower rails secured to the structure, the upper rails being slidably disposed on the lower rails so that the seat proper is slidable relative to the vehicle floor, a seat belt having ends which are respectively connected to side frames of the seat cushion part through respective retainers, two brackets respectively connected at their upper ends to the retainers, each bracket having a lower end formed into a first engaging portion, and a second engaging portion defined by either one of the structure and the vehicle floor, the first and second engaging portions interlocking with each other in such a manner that the first engaging portion is slidable with respect to the second engaging portion.
  • FIG. 1 is a sectional view of a seat belt-equipped seat assembly of a first embodiment of the present invention, which view is taken from a front of the seat assembly;
  • FIG. 2 is a perspective view of an arrangement employed in the seat assembly of the first embodiment of FIG. 1;
  • FIG. 3 is a perspective view of a rotatable frame employed in the seat assembly of FIG. 1 for horizontally turning the seat proper relative to a vehicle floor;
  • FIG. 4 is a view similar to FIG. 1, but showing a second embodiment of the present invention.
  • FIG. 5 is a view similar to FIG. 1, but showing a conventional seat belt-equipped seat assembly.
  • FIGS. 1 to 3 there is shown a seat assembly of a first embodiment of the present invention.
  • the seat assembly 1 of this embodiment is provided by modifying the conventional seat assembly of FIG. 5.
  • substantially the same parts as those of the conventional seat assembly are designated by the same numerals and detailed explanation of them will be omitted from the following description.
  • the seat assembly 1 comprises a seat cushion part 2 and a seat back part 3 between which a known reclining mechanism is arranged.
  • Parallel upper rails 5a and 5b are secured to lower side frames 4a and 4b of the seat cushion part 2, which are slidably disposed on parallel lower rails 6a and 6b secured to a rectangular rotatable frame 7.
  • the rotatable frame 7 is rotatably disposed on a support member 8 through the afore-mentioned turning connection.
  • the support member 8 is stationarily mounted on a vehicle floor 9.
  • the seat proper is horizontally rotatable and horizontally linearly movable relative to the vehicle floor 9.
  • the seat belt assembly is mounted to the seat assembly 1 in such a manner as will be described in the following.
  • the rectangular rotatable frame 7 is formed at the laterally opposed sides with downwardly extending flanges 13a and 13b which act as guide rails as will be apparent as the description proceeds.
  • the connection of the seat belt retainers 11a and 11b to the lower side frames 4a and 4b of the seat cushion part 4 is made through enlarged brackets 12a and 12b each being bolted to the corresponding lower side frame 4a or 4b.
  • the belt retainer 11a or 11b is pivotally connected to the bracket 12a or 12b through one of the bolts.
  • Each bracket 12a or 12b has a channel-shaped lower portion 12c or 12d into which the flange 13a or 13b of the rotatable frame 7 is slidably received.
  • the brackets 12a and 12b move along the flanges 13a and 13b with the channel-shaped lower portions 12c and 12d kept interlocked with the flanges.
  • the load is transmitted or dispersed to not only the lower side frames 4a and 4b of the seat cushion part 2 but also the seat turning mechanism, unlike the case of the afore-mentioned conventional seat assembly.
  • the load is transmitted or dispersed to not only the lower side frames 4a and 4b of the seat cushion part 2 but also the seat turning mechanism, unlike the case of the afore-mentioned conventional seat assembly.
  • deformation and/or breakage of the side frames 4a and 4b does not occur.
  • FIG. 4 there is shown a seat assembly of a second embodiment of the present invention.
  • the seat assembly 1 of the second embodiment comprises a seat cushion part 2 and a seat back part 3 between which a known reclining mechanism is arranged.
  • Parallel upper rails 5a and 5b are connected through cross beams (no numerals) to lower side frames 4a and 4b of the seat cushion part 2.
  • the upper rails 5a and 5b are slidably disposed on parallel lower rails 6a and 6b which are secured to the vehicle floor 9 through mounts 15. With this, the seat proper is horizontally linearly movable relative to the vehicle floor 9.
  • connection of the seat belt retainers 11a and 11b to the lower side frames 4a and 4b of the seat cushion part 4 is made through elongate brackets 12a and 12b each being secured to the corresponding lower side frame 4a or 4b.
  • the belt retainer 11a or 11b is pivotally connected to the bracket 12a or 12b.
  • the brackets 12a and 12b have channel-shaped lower portions 12c and 12d which are slidably received in respective grooves 14a and 14b formed in the vehicle floor 9.
  • the grooves 14a and 14b have longitudinally extending flanges 14c and 14d which are put in the channels of the corresponding brackets 12a and 12b.
  • the load is transmitted or dispersed to not only the lower side frames 4a and 4b of the seat cushion part 2 but also the vehicle floor 9.
  • the undesired deformation and/or breakage of the side frames 4a and 4b does not occur.
